IMPROVEMENT IN PLASTER CEILINGS., CORNICES, &c.

Specification forming part of Letters Patent No. 183,369, dated October17, 1876; application filed August 3,1876.

-secured in position.

The object of my invention is to produce ornaments that will not crack,fall off, or blister, and that shall be earthquake-proof, as Will morefully appear hereafter.

Figure 1 of the accompanying drawings shows a center-piece constructedafter my invention, with a portion of the plaster broken away to exposethe frame or body. Fig. 2 is a view of the under side of the frame orbody before the plastering is applied.

The base or body oi the ornament to be made, Whether a center-piece orcornice, is Iirst formed of a frame composed of strips of wood or metaljoined together into the desired shape and size of the ornament, andupon and over this frame-work is stretched a netting or gauze of wire orfibrous material, having meshes sufficiently open to allow the plasterto engage with and adhere to it. Over and upon this is laid the coatingof plaster, and the netting is pressed up more or less into the shape tobe given to the ornament, so that the parts that project or stand out inrelief may be strengthened by the netting or gauze that is in thismanner incorporated with the plastering.

In the drawing, t a represent the netting or gauze of wire or fibrousmaterial; b b, the frame-work formed of strips of Wood or metal, and c cthe partsof the netting that are bent over and secured to the frame.rlhe plaster A is spread over this frame-Work or body,

and molded after the usual method of forming ornaments of this characterto any desired pattern or figure, andl when finished and sufficientlyset,- the ornament is secured in place' by means of screws insertedthrough the holes provided in the frame and through the plaster, asshown in Fig. l of the drawlng. l

This plastering can be made in partsor sections of any convenient size,more or less ornamented, and then secured in place upon ceilings orwalls. It can be laid over old plastering, wainscoting, orwood-sheathing, and thus form a covering that will not crack, fall off,or blister.' These quali-ties render it of great value in countriesvisited by earthquakes.

The gauze or netting a a may be either of wire or of fibrous material,but the meshes should be sufficiently Wide or open to allow theplastering to be worked through and be combined with the strands orfibers. It may be secured to the frame-work by turning over the edgesand securing them on the under side, or by stretching and tacking itover the v frame.

Having thus fully described the nature and operation of my invention,what I claim therein as new, and desire to secure by Letters Patent, is-

As a new article of manufacture, an ornament adapted to be secured inposition, consisting of a frame, b, netting a, stretched over the same,and plaster A, spread over the'netting, substantially as described andshown. 1n witness whereof l have hereunto set my hand and seal this 12thday of July, A.
